CVE-2025-27207: Adobe Commerce B2B Privilege Escalation Flaw

CVE-2025-27207 Overview

CVE-2025-27207 is an Improper Access Control vulnerability [CWE-284] affecting Adobe Commerce and Adobe Commerce B2B. The flaw allows a low-privileged attacker to bypass authorization checks and gain unauthorized read access to protected resources. Exploitation does not require user interaction and can be performed remotely over the network.

Affected releases include Adobe Commerce versions 2.4.8, 2.4.7-p5, 2.4.6-p10, 2.4.5-p12, 2.4.4-p13, and earlier. Adobe addressed the issue in security advisory APSB25-50.

Critical Impact
An authenticated attacker with low privileges can escalate access and read confidential data from Adobe Commerce storefronts without user interaction.

Technical Details for CVE-2025-27207

Vulnerability Analysis

The vulnerability stems from insufficient access control enforcement within Adobe Commerce. An authenticated user holding low privileges can issue crafted requests to endpoints that fail to validate the caller's authorization scope. The result is unauthorized read access to data that should be restricted to higher-privilege roles.

The attack does not require social engineering or client-side interaction. The confidentiality impact is high, while integrity and availability remain unaffected. This scope makes the flaw well-suited for reconnaissance, data harvesting, and lateral movement within multi-tenant storefronts.

Root Cause

The root cause is an Improper Access Control weakness [CWE-284] in the affected Commerce components. Authorization checks are missing or incorrectly applied on protected code paths, allowing a low-privileged session to reach resources reserved for administrative or elevated roles.

Attack Vector

Exploitation occurs over the network against an authenticated Adobe Commerce session. An attacker uses valid low-privilege credentials, such as a customer or restricted staff account, to submit API or storefront requests targeting the deficient authorization path. Adobe has not published detailed exploitation mechanics, and no public proof-of-concept exists.

Refer to the Adobe Security Advisory APSB25-50 for authoritative technical details.

Detection Methods for CVE-2025-27207

Indicators of Compromise

Unexpected read operations against admin or B2B GraphQL and REST endpoints from customer-scoped tokens.
Anomalous API call patterns from low-privileged accounts accessing customer, order, or company data at scale.
Sudden spikes in GET requests to /rest/V1/ endpoints outside normal storefront workflows.

Detection Strategies

Correlate authentication scope with resource access in web server and application logs to identify authorization mismatches.
Baseline API usage per user role and alert on deviations, particularly bulk enumeration by customer-tier accounts.
Review Adobe Commerce audit logs and admin action logs for privilege-inconsistent operations.

Monitoring Recommendations

Enable verbose access logging on the Adobe Commerce web tier and forward events to a centralized SIEM.
Monitor GraphQL query patterns for high-cardinality field selection from unauthenticated or low-privileged contexts.
Track failed and successful admin API calls, alerting when non-admin tokens receive 200 OK responses.

How to Mitigate CVE-2025-27207

Immediate Actions Required

Apply the Adobe Commerce security patches referenced in APSB25-50 to all affected storefronts.
Inventory Adobe Commerce and Commerce B2B installations and confirm patch level against the affected version list.
Rotate credentials and API tokens for any accounts that may have been abused prior to patching.

Patch Information

Adobe released fixes for Adobe Commerce and Adobe Commerce B2B in advisory APSB25-50. Administrators should upgrade to the patched builds identified for their branch (2.4.8, 2.4.7-p5, 2.4.6-p10, 2.4.5-p12, or 2.4.4-p13 patch releases as listed by Adobe). See the Adobe Security Advisory APSB25-50 for exact patch identifiers.

Workarounds

Restrict access to Adobe Commerce admin and API endpoints via IP allowlists and web application firewall rules where feasible.
Reduce the privilege footprint of customer and staff accounts to the minimum required scope.
Disable unused REST and GraphQL endpoints exposed by third-party modules until patching is complete.
